Definitions

  • This invention relates to a sley drive for a weaving machine.
  • sley drives for weaving machines have employed oscillating sley shafts in order to impart pivoting, i.e. oscillating motion to a reed for beat-up purposes.
  • the center of gravity of the unit formed by the parts pivoted by the sley shaft e.g. sley levers, sley, reed, shuttle guide, driving cam follower
  • the center of gravity of the unit formed by the parts pivoted by the sley shaft is relatively far away from the sley shaft axis, for instance, by an amount corresponding to half the distance between the top end of the reed and the sley shaft axis.
  • the invention provides a sley drive for a weaving machine comprising a sley shaft mounted for oscillation about a longitudinal axis, a reed and means coupling the reed to the sley shaft for oscillation about the axis of the sley shaft wherein the coupling means includes a balance weight opposite the reed relative to the axis of oscillation so that the center of gravity of the reed and coupling means is coincident with the axis of oscillation.
  • a particular achievement of the sley drive is that, as calculations and tests show, there is a reduction in the components of force arising from the sley shaft and transmitted to the whole machine and in the associated vibrations. More particularly, the horizontal force components which arise in the conventional construction can, to a large extent, be converted into vertical force components which, as a rule, can more readily be taken up by the whole machine frame, particularly by a central support, than can horizontal components since the central support of a weaving machine usually has a cross-section extending principally vertically, i.e. the vertical extent of the support is greater than the width. The sley drive is thus able to reduce the vibrations and noise of the machine.
  • the balance weight is embodied by at least one shaft section which extends parallel to the sley shaft and which is disposed between two sley-shaft bearings.
  • the shaft section is connected by a means such as crank-web-like coupling members to the sley shaft while the reed is secured via a sley and sley levers to the shaft section.
  • the sley shaft is interrupted near the shaft section. Consequently, despite the weight balancing, the sum of the weights of the parts secured to and pivotally reciprocated by the sley shaft viz. the sley levers, sley, reed and, where applicable, cam follower levers and a shuttle guide, is substantially the same as in the known sley drive construction having a continuous sley shaft and no weight balancing.
  • the sley levers and/or the offset shaft section are hollow members. This feature helps to keep the moment of inertia of the unit formed by the above-mentioned parts down to substantially the same level as for the known sley drive.
  • FIG. 1 diagrammatically illustrates a front elevational view of a sley drive according to the invention of a gripper shuttle weaving machine
  • FIG. 2 illustrates a view taken on line II--II of FIG. 1;
  • FIG. 3 illustrates a detail of a sley lever in accordance with the invention
  • FIG. 4 illustrates a view taken on line IV--IV of FIG. 3;
  • FIG. 5 illustrates a detail of a coupling member in accordance with the invention
  • FIG. 6 illustrates a view in the direction of the arrow VI of FIG. 5.
  • FIG. 7 illustrates a cross-sectional view of a modified shaft section according to the invention.
  • a weaving machine of the gripper shuttle type includes a reed 4 for beating-up weft yarns as is known.
  • the reed 4 is reciprocated back and forth in an oscillating manner.
  • the reed 4 is mounted on a sley 3 and oscillated by a sley drive which, in turn, is driven off a main shaft 8 of the weaving machine.
  • the main shaft 8 passes through and is mounted in a series (three) of sley boxes or bearings 7.
  • the sley drive includes a sley shaft which is interrupted so as to have a plurality of sley shaft portions 13 located coaxially about a longitudinal axis 19. Each portion 13 is mounted for oscillation in a respective bearing 7 about the axis 19 and extends out of the bearing 7 at both sides.
  • a means is provided to oscillate the sley shaft portion 13 and includes a pair of cams 9, 10 secured in each bearing 7 to the main shaft 8, cam 9 being operatively associated with a roller 11 of a cam follower 12 secured to the shaft portion 13 in the bearing 7 while cam 10 is operatively associated with a roller 11a of the cam follower 12a also secured to the shaft portion 13 in the bearing 7.
  • a means for coupling the reed 4 to the sley shaft portions 13 includes a balance weight in the form of a shaft section 15 opposite the reed 4 relative to the axis 19 of oscillation.
  • This means includes a means, such as a coupling member 14, at each end of the shaft section 15 which couples the shaft section 15 to a respective sley shaft portion 13 for oscillation with the sley shaft portions 13 and a means coupling the reed 4 directly to intermediate portions of the shaft section 15 for oscillation with the shaft section 15.
  • This latter means includes the sley 3 and a plurality (e.g. three) of sley levers 16 which are secured to the shaft section 15. As shown, the shaft section 15 is located on an axis parallel to the axis 19 of the sley shaft portions 13 and is offset from these portions 13.
  • each sley lever 16 is secured to each shaft portion 15, by being clamped by a screw 17. Also, each lever 16 is hollowed so as to form a weight-reducing chamber 18 (FIG. 4).
  • each coupling member 14 is formed with two bores 21, 22 for receiving the respective sley shaft portion 13 and shaft section 15 and is secured to each via screws 26, 27, respectively.
  • the sley 3 carries a shuttle guide formed of guide teeth 2 for a picking element, viz. a gripper shuttle; only one such tooth is visible in FIG. 2.
  • the shaft section 15 which acts as a balance weight is of corresponding weight to the removed portions of the sley shaft, i.e. the portions between the shaft portions 13.
  • the shaft section 15 serves to dispose the center of gravity 23 of the reed 4 and the means coupling the reed 4 to the sley shaft portions 13 (i.e. the coupling elements 14, shaft section 15, sley levers 16, sley 3 and where applicable, the shuttle guide 2 and cam followers 11, 11a, 12, 12a) coincident with the axis 19 of oscillation of the sley shaft.
  • the unit composed of those parts oscillated in operation during beating-up by the sley shaft 13 in the direction indicated by a double arrow 24 oscillate about the sley shaft axis 19 a reduction in vibration is achieved.
  • FIG. 2 shows the center of gravity 25 obtained when a continuous sley shaft without parallel offset portions is used.
  • the weight of the unit composed of the coupling members 14, shaft sections 15, sley levers 16, sley 3, reed 4 and shuttle guide 2 which is moved by the sley shaft 13 or the cam followers 11, 11a, 12, 12a is about the same as the weight of a corresponding continuous sley shaft and of the associated unit parts thereof. Consequently, the moment of inertia of the unit 14, 15, 16, 3, 4, 2 relative to the axis 19 is approximately the same as for a sley drive having a continuous sley shaft.
  • the shaft portions 15 take the form of hollow section members (tubes) 15a as another weight-saving step.
  • the sley levers 16 can be made of light metal or a plastics.
